COMBINATION-WINDLASS FOR VESSELS.

Specification of Letters Patent.

Application filed April 30, 1912, Serial No. 694,230. Renewed June 3, 1913. Serial No. 771,528.

the drum thereof to be actuated at high speed when no great power is required,and to enable additional power to be applied while operating the windlass at slower speed when the strain becomes greater.

Further objects are to provide improvements which I shall now proceed to describe and claim.

Of the accompanying drawings,Figure 1 is a plan view of the stem or bow portion of a vessel provided with my improvements.

Fig. 2 represents a section on line22 of Fig. 1. Fig. 3 represents an elevation of the mechanism, looking from the left of Fig. 1. Fig. 4 represents a section on line H of Fig. 1. Fig.5 is a detail section through the hawser pipe.

Similar reference characters indicate the same or similar parts in all of the views.

A portion of the bow or stem of the vessel is indicated at 10, and a deck section at 11.

The bow-sprit 12 at its inner end extends under a block 13 and the inner ends of the said bow-sprit and block bear against a stanchion 1A. The block 13 has its upper side cut away for a purpose presently described, and said cut away portion is covered or protected by a guard 15. At each end of the space provided by the cut away portion of the block 13 are hooks 16. It is to'be understood, however, that said hooks may be eyes. A tackle 17 has one end connected to the shank of an anchor 18, the said tackle being attached to the hooks l6 and having one end connected to any suitable cleat. A second anchor is shown at 19, and both of these anchors are indicated as of the mushroom type. As is usual, one of the anchors is heavier than the other. The shanks of the anchors are shown as extending through the hawse holes 20, across the lower portions of which extend rolls 21 adapted to ease the movements of the anchors and their cables or hawsers. The larger anchor 18 is shown as having a chain cable 22 connected to it, while the smaller anchor 19 is shown as having a hawser 23,.connected to it. The cable and the. hawser are coiled as usual aroundthe drum or roller of the windlass. The cable and hawser engaging parts of the drum may have their surfaces composed of the usual whelps, but for convenience of illustration they are shown as smooth. For brevity of description, the rotary portion of the windlass will be hereinafter referred to as the drum. Said drum has its gudgeons mounted in checks or bits 25. For the chain cable 22 the usual chain pipe 26 is provided so as to guide the chain down into the usual chain box below deck. Adjacent the portion of the drum which engages the hawser 23, I provide'a capstan or hawser rack 27 mounted to rotate on a vertical axis and rising from the deck in position to receive and coil the hawser 23 as it comes from the windlass, said capstan or rack taking up but little room and also holding the hawser and keeping it from slipping around the windlass drum. This capstan or hawser rack enables one man to dispose of the hawser while fre quently several men are required to hold the hawser and stow it.

The windlass drum isprovided with gears 28 which are engaged by pinions 29 carried bearings carried by brackets 82 supported.

by the stanchion 1 1.

The middle portion of the windlass drum is notched or toothed at 33 as usual, the teeth of this portion being engaged by a gravity or sliding pawl 34 of a well known type. Suitable means may be provided for holding the pawl elevated, as by providing the upper end of the pawl with a groove 35 (Figs. 2 and 3) which is open at one end in order to receive the crank-shaped end of a retainer 36 pivotally supported by the stanchion 14. By lifting the pawl 34 and then swinging the retainer into the groove 35, the said pawl may be held in inoperative posit-ion.

Bits of a usual form are indicated at 37.

In order to aid the crank shaft When desired in imparting rotation to the drum, I

employ gypsy assistants comprising levers 38 pivoted on the counter-shaft 30 and having pawls 39 adapted to engage ratchet wheels 40 carried by the drum. Said levers are shown as provided with removable handspikes 41. By working these levers up and down, their pawls coact with the ratchet wheels so as to enable great strain to be overcome, although of course the operation will be at slower speed than can readily be effected by the crank shaft and gearing alone. ll hen these gypsy assistants are not needed for use, or when the gravity pawl is raised for the purpose of permitting the drum to let out the cable or hawser, the levers 38 may be thrown over to the dotted line position of Fig. 2, stops 42 projecting from the block 13 being provided to support said levers in their inoperative positions.

The gudgeons 43 of the drum are provided with smooth peripheral portions best indicated in Fig. 4, with which portions strap brakes 4A are adapted to cooperate in retarding rotation of the drum. Each of said brakes 44 consists of a resilient bar bent approximately to conform to the periphery of the gudgeon against which it may bear. Said brake 44 is secured at 45 to a pin projecting from a cheek or hit 25, the outer end of said brake being provided with a handle or treadle 46. Secured to the deck are two hook-shaped detents 47 under which the handles or treadles 46 can be caught when braking action is to be effected, the proportions of the parts being such that when the handles or treadles 46 are engaged with the hooked detents L7, the brakes 4.4 will exert some retarding effect upon the drum, which retarding effect may be increased by downward pressure upon the handles or treadles.

I claim:

1. A combination Windlass, comprising a rotary drum having cable and hawser portions and an intermediate toothed portion,

tions and an intermediate toothed portion,

said drum having also gears and ratchet wheels, a detent pawl for the toothed portion of the drum, a counter shaft having cranks and provided with pinions engaging said gears, levers pivoted on said counter shaft and having pawls to engage the ratchet wheels of the drum, said levers being movable from one side to the other of the windlass drum to carry the pawls away from the ratchet wheels, and stops for supporting the levers in their inoperative positions.

3. A combination Windlass, comprising a rotary drum having cable and hawser por tions and an intermediate toothed portion, said drum having also gears and ratchet wheels, a detent pawl for the toothed portion of the drum, a counter shaft having cranks and provided with pinions engaging said gears, levers pivoted on said counter shaft and having pawls to engage the ratchet wheels of the drum, said drum having smooth peripheral portions, resilient brakes engaging said smooth portions of the drum and having operating projections, and detents for engaging the operating projections to hold the brakes in contact with said smooth peripheral portions of the drum.

In testimony whereof I have affixed my signature, in presence of two Witnesses.

JOHN A. WATT.
